STOVE-BACK.

SPECIFICATION forming part of Letters Patent No. 302,345, dated July 22,1884. Application filed September 22, 1883. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN LANE, of Hyde Park, in the county of Cook andState of Illinois, have invented a new and useful Improve ment inStove-Backs, which improvement is fully set forth in the followingspecification.

My invention relates to what may be called a two-high-sectionstove-backi. 6., one section above another throughout its length, inwhich the arch-section is made separate and above the back proper ormain section, and both sections made in parts. It is well known thatsuchstove-backs, made in sections, and the sections in parts, have beensubject to the trouble of some one or more parts getting out of place,and the back thereby becoming loosejointed, rickety, and tumble-down,caused by the contraction and expansion of the back under heat and coldthat it is subject to; and the object of my invention is to so constructa stove-back in sections and the sections in parts in such a manner asto avoid such troubles.

The invention consists in certain improvements, which will first bedescribed in the specification and afterward pointed out in the claim.

Referring to the drawings, like letters refer to like parts in all thefigures, in which Figure l is a face or front view of my llll' provedstove-back. Fig. 2 is a rear view of same. Fig. 3 is a bottom edge view,and Fig. 4 is a perspective view, of the upper section or arch-plates,showing how they are provided with a tongue along their bottom edge andhow telescoped, one plate within the other. Fig. 5 is a perspective viewof one of the end wings or back plates. Figs. 6 and 7 are end views ofsame' shown in Fig. l, by which is seen that the grooves in the backplate are in the rear part of the stove-back and protected from greatheat by the plates in front.

A represents the central plate, provided with a corrugated face andplain flat ends and top, as shown, and as the central plate receives thebrunt of heat and is most subject to warp and twist by heat, it is madeessentially plain and flat, without grooves, 'tongues, or other holdingdevices, save a bolt-hole, d, at each end, as shown.

constructed with an offset shoulder, e, by which the upper part of thesaid plate is set back hehind the top plates, with slots g, by which thesaid back plate may be adj ustably attached to the central plate, andgrooves f, which preferably extend the length of the said plate forseating the tongue of the top plates, all of which will be fullyunderstood by the draw ings. The said central plate, A, with two saidback plates or end wings, B, constitute the lower section of my improvedstove-back, and the upper section of the said stove-back consists of thetwo arched top plates, 0 and O, as shown in the drawings.

0 represents the outer top plate, constructed of thin plate, with itstop edge arching rearwardly for the purpose of abutting on thestovecasting, and the bottomedge is provided with a tongue, is,projecting rearward and extending the entire length of the said topplate.

The said tonguek is seated in one of the grooves I -f in the back plate,and may be adjusted up or down to other grooves, by which the said topplate is made adjustable vertically to fit stoves of variable heights.In length the said top plate is about equal with the center plate, A, asshown in the drawings.

0 represents the inner top plate,which is constructed in the same manneras the outer top plate, 0, with its top edge arched, and its bottom edgeprovided with the tongue k, and the description thereof will sufficetforthis. The said two top plates 0 and Uare made telescopic, one within theother. The said plate G is adapted to fit and slide inside of the saidplate 0, the arched top edge of the plate 0 covering the arched top edgeof the plate 0, and the tongue k of the plate 0 extending andoverlapping the bottom edge and tongue of the plate 0. As it were, theone is boxed within the other, by which the two said plates 0 and C arenot liable to get separated or out of place or twist and warp underheat. The said tongue 7c on the inner top plate, 0, is seated in agroove, f, just above the groove in which the tongue of the outer plate,0, is seated, and the two said plates maybe adjusted vertically thereonwithout changing their relative position with each other, and the twosaid top plates, 0 and C, may be adjusted laterally by being drawn apartto fit stoves of different widths, as will be understood by thedrawings.

The operation of my improved stove-back is simple and will be understoodby the drawings. The live parts are. assembled into their position, thetwo bolts cinserted, and the nuts h screwed up tight, by which all theparts are held in position, and by loosening the said nuts the two topplates may be adjusted both vertically and laterally, and the backplates or end wings adjusted laterally to fit any sized stove, and thesaid nuts, when again tightened, will hold the parts rigidly inposition.

The central plate may warp, twist, and burn out, and be changed for anew one, while the back plates or end wings and top plates remain good,perfect, and in correct position, and by which the said stove back isnot liable to get rickety or tumble down.

I am aware that it is not new to construct astove-back of separatepieces or sections adjustable to fit stoves of different sizes, constructed as shown in Patents No. 237 ,450, issued February 8, 1881, andNo. 221,513, issued November 11, 1879. Therefore I do not broadly claimsuch, my improvements having the advantage of being more substantial anddurable by reason of the peculiar and improved construction of the saidtop plates and back plates, and the locking and tying in the rear, whichsaid looking or tying is covered and protected from excessive heat bythe central plate in front, as shown.

I claim In a stove-back, the combination of a central plate and two backplates or end wings, the said back plates provided with the offsetshoulders, the slots, and the grooves, with the two top plates providedwith arched upper edges, and their bottom edges provided with thetongues projecting rearward and eX- tending throughout their length, thetongue of the outer plate overlapping the bottom edge and tongue of theinner plate, and the inner plate telescopic within the outer plate, andthe bolt 0, with nut h, substantially as and for the purpose set forth.-

JOHN LANE.
